Electrical Bus Bar Panel

Single pole circuit breakers provide 120 volts and connect to just one hot bus bar.

Electrical bus bar panel. The bus bar in your home s electrical panel is the long bar on one or both sides of the panel that contain many of the electrical lines in your home s wiring. They are also used to connect high voltage equipment at electrical switchyards and low voltage equipment in battery banks. At the back of the panel box the two bus bars vertical strips of metal that connect to each breaker to supply power to the wiring are separated in the middle with all of the main breakers connected to the top bus sections. A bus bar is an electrical conductor or group of conductors that is used to collect and distribute electrical power.

Ring busbar bars connected to form a ring using switched couplers. In electric power distribution a busbar also bus bar is a metallic strip or bar typically housed inside switchgear panel boards and busway enclosures for local high current power distribution. Busbars are maintained at specific voltages and are typically capable of carrying high currents. An electrical bus bar is defined as a conductor or a group of conductor used for collecting electric power from the incoming feeders and distributes them to the outgoing feeders.

It also identifies your breaker panel s amperage capacity. In other words it is a type of electrical junction in which all the incoming and outgoing electrical current meets. 0 17 10 2 12 2 13 2 14 5 15 3 18 1 1 9 21 2 23 2 27 1. Busbars can be found in electrical panels where they act as a junction of sorts for incoming and outgoing currents.

Circuit breakers snap into place onto one or both of the bus bars to provide power to the circuits.

Large two pole circuit breaker that limits the amount of electricity coming in from outside to protect the circuits it feeds. Electrical panels protective devices.

The positive black or hot wires run from the the circuit breakers while the neutral white and ground bare copper wires run to the bus bar completing the circuit.

The two thick black service wires feeding the main circuit breaker each carry 120 volts from the electric meter and feed the two hot bus bars in the panel.
